We used two gametocidal (Gc) chromosomes 2C and 3C(SAT) to dissect barley chromosome 4H added to common wheat. The Gc chromosome induced chromosomal structural rearrangements in the progeny of the 4H addition line of common wheat carrying the monosomic Gc chromosome. We conducted in situ hybridization to select plants carrying rearranged 4H chromosomes and characterized the rearranged chromosom...

4H-1,4-oxazines were designed as transthyretin (TTR) amyloid fibril inhibitors based on an analysis of the interactions between known small molecule inhibitors and TTR by molecular docking. A series of 2,4,6-triaryl-4H-1,4-oxazines was synthesized by the cyclization of N,N-bis(phenacyl)anilines with POCl3 in pyridine. Inhibition of TTR amyloid fibril was evaluated by a fibril formation assay. T...

background: recently, the anti cancer effect of chromene derivatives in different cell types has been reported. in this study, we report some derivatives of dihydropyrano[c]chromenes with growth inhibitory and apoptotic activity against k562, chronic myeloid leukaemia (cml). methods: the cells were seeded in 96-well plates at 1×105 cells/well and treated with different concentrations of the dih...

Phenolic compounds present in Lolium multiflorum Lam. were isolated and characterized. Significant differences in their distribution were found, in shoots and roots of plants with (Lmþ) and without (Lm ) endophyte association, grown with (Micþ) and without (Mic ) mycorrhizal fungi Glomus intraradices, indicating a systemic effect of these microorganisms on the phenolics metabolism of L. multifl...

A novel HAuCl4@UiO-66-NH2 material has been obtained and utilized as a heterogeneous Au(III) catalyst. This Au(III) catalyst was able to promote the formation of a variety of dihydrochalcones starting from 2H-chromenes in moderate to good yields. A tandem hydride shift/hydration reaction sequence has been proposed based on deuterium labeling studies, which revealed a 1,5-hydride shift reaction ...

A series of optically active pyrano[3,2-c]chromenes have been synthesized through an asymmetric domino reaction of 4-hydroxy-2H-chromen-2-ones with malononitriles. The targeted molecules were obtained in excellent yields and enantioselectivities (up to 94% yield, 99% ee). The AChE inhibitory activity studies revealed that compounds 4n (IC50 = 21.3 μM) and 4p (IC50 = 19.2 μM) displayed potent ac...

BACKGROUND Similar as in vascular endothelium the negatively charged glycocalyx of erythrocytes selectively buffers sodium. Loss of glycocalyx (i.e. loss of negative charges) leads to increased erythrocyte sodium sensitivity (ESS) quantified by a recently developed salt-blood-test (SBT). The hypothesis was tested whether a regular 4-hour hemodialysis (4h-HD) alters ESS. METHODS In 38 patients...

Title of Thesis: CHARACTERIZATION OF 4H-SiC MOSFETs USING FIRST PRINCIPLES COULOMB SCATTERING MOBILITY MODELING AND DEVICE SIMULATION Siddharth Potbhare Master of Science, 2005 Thesis directed by: Professor Neil Goldsman Department of Electrical and Computer Engineering Detailed analysis of a 4H-SiC MOSFET has been carried out by numerically solving the steady state semiconductor Drift-Diffusio...

Gas-liquid chromatography-mass spectrometry (GLC-MS) has been used for the separation, detection, and identification of 1,4-benzoxazin-3-ones (hydroxamic acids and lactams) and benzoxazolinones found in maize (Zea mays L.) extracts. Compounds of interest were partitioned into ethyl acetate from aqueous maize seedling extracts. For analysis by GLC-MS, trimethylsilyl derivatives were prepared, ch...
